EXPLOSIVE-Y-ENGINE.

SPECIFICATION forming'part of Letters Patent No. 617,978 dated. January 17, 1899.

Application filed January 20,1898. Serial No. 667,284. (No model.) I

To all whom it may concern.-

Be it known that I, ALEXANDER W INTON, a citizen of the United S'tates,.residingat Cleveland, in the county of cuyahoga and State of Ohio, have invented certain new and useful Improvements in Explosive-Engines; and I do hereby declare the following to be a full, clear,

and exact description of the invention, such as will enable others skilled in the art to which it appertains to'make and use the same.

My invention relates to improvements in explosive-engines, and pertains to that class of engines in which gasolene is used as the means of generating an explosive compound.

The object of my invention is to provide in a single-cylinder engine a means for counter-- balancing the momenturnof the piston and its pitman, which overcomes all vibration, malt-- ing asmooth-running engine, with considerably less wearupon the parts than where a single-piston engine isnot provided with means for balancing its piston. and 'pitman,

and especially is this true in respect to explosive-engines which are very rapid in their movements, as will be readily understood by those skilled'i'n the art. 1

I- My present invention is especially intended for and peculiarly adapted to he used as a propelling means for motor-vehicles, in which it is very'desirable to have a smooth-running engine with as litte vibration as possible. [In the accompanying drawings, Figure 1 is a 'sideelevation of an engine embodying my invention. Fig: 2 isa top plan view of apart of the engine, showing my invention.

In the accompanying drawings a, indicates the cylinder of am explosive-engine; b, the.

drive-shaft thereof 5 c, a balance-weight; b

the drive-shaft crank; (Z, the pitman, and fhas one end con n'cctcd with the cccentriestrap and carries at its opposite end a balancingweight g. This balancing-weight is supported by a rock-arm B, the opposite end of the rockarin being supported bya shaft or spindle E.

The eccentric A is positioned upon the drive shaft exactly opposite the crank 12*, as clearly illustrated in the drawings. \Vhen an explosion occurs and the'piston is driven the eccentric reciprocates the balance-weight g back and forth in a straight or substantially a straight line and in opposite directions to the reciprocation of the piston and its pitman, and owing to this opposite movement of the balancing-weight and its momentum it balances the momentum of'the piston andthe pitmau. By means of a balancing device of this charae'terl am able to produce a rapidly-running single-cylinder explosive engine in which the usual vibration is practically avoid ed. \Vhile I show and prefer to use an eccentric for this Weight, in will be readily understood that a.

crank may be substituted therefor, though the eccentric is much preferred.

Having thus described my invention, what I claim, and desire to secure by Letters Patent,is I

1. An engine comprising a drive shaft, having a crank, a piston. connected with the crank, a balancing-weight, the drive-shaft provided with an eccentric positioned thereon in opposition to said crank, and a connection between the weight and the eccentric whereby the piston and the weight move in opposition.

2. An engine comprising a reciprocating piston, a drive-shaft and a crank, an eccentrio-rod having an eccentric-strap at one end and a balancing-weight at its other end, the eccentric being positioned upon the driveshaft in opposition to the crank for the purpose described 3. An engine comprising a reciprocating piston, a drive-shaft, a crank, an eccentricrod having an eccentricrstrap at one end and a balancing-weight at the other end, and a vertically disposed rock-arm having one end pivoted and. its opposite end pivotally connected with and supporting the said weight for the purpose described.

4. An engine comprising a reciprocating piston,a drive-shaft connected with the piston, a vertically-disposed rod'pivoted at one end and carrying :i'weightnt its opposite end, and a connection between the piston and the weighted free end of the rod, substantially as described.

5. An engine comprising a reciprocating piston, a drive-shaft, having a crank, an eccentric nponthe shaft positioned in opposi; tion to the cranlg-a vertically-disposed rod pivoted at one end, a weight carried by the free end of the rod, and an eccentric rod or pitrnan having one end provided with an eccentric-strapencircling the eccentric cf the drive-shaft, and its, opposite end connected with the free weighted end of the pivoted rod,

substantially as described.

(5. An engine comprising a reciprocating piston, a vertically-disposed rod pivoted at one end and extending'in'a direct-ion across the line of travel of the piston, a weight supported by the free end of the rod practically in a, horizontal line with the piston, and aconnection between the weight and the piston tomove the weight in the opposite direction to the movement of'the piston, siib'stsmtially' as described. i

In testimony whereof I affix my signature in presence of two witnesses.

ALEXANDER W INTON.
